## About

This is a memcached client library which can set tag(s) and delete by tag

## Installing

### Using *go get*

    $ go get github.com/dakimura/memctag/memcache

## Usage

    package main

    import (

        "fmt"

        "github.com/bradfitz/gomemcache/memcache"

        memcacheWithTag "github.com/dakimura/memctag/memcache"

    )

    func main(){

        // initialize memcached client

        mc := memcacheWithTag.NewClient("127.0.0.1:11211")

        tags := []string{"1-tag", "2-tag"}

        tag := []string{"1-tag"}

        item := memcache.Item{Key: "1:message", Value: []byte("cache1")}

        item2 := memcache.Item{Key: "2:message", Value: []byte("cache2")}

        item3 := memcache.Item{Key: "3:message", Value: []byte("cache3")}

        // set cache with tag(s)

        mc.SetWithTags(&item, tags)

        mc.SetWithTags(&item2, tags)

        mc.SetWithTags(&item3, tag)

        printCache(mc.GetWithTags("1:message", tags)) //"1-tag", "2-tag"

        printCache(mc.GetWithTags("2:message", tags)) //"1-tag", "2-tag"

        printCache(mc.GetWithTags("3:message", tag))  //"1-tag"

        // you can delete all caches which have been set with the tag

        mc.Delete("2-tag")

        printCache(mc.GetWithTags("1:message", tags)) // -> cache miss

        printCache(mc.GetWithTags("2:message", tags)) // -> cache miss

        printCache(mc.GetWithTags("3:message", tag))  // -> "cache3"

        // also you can delete it by the cache key

        mc.Delete("3:message")

        printCache(mc.GetWithTags("3:message", tag))

    }

    func printCache(item *memcache.Item, err error) {

        if err != nil {

            fmt.Println(err.Error())

        } else {

            fmt.Println(string(item.Value))

        }

    }
